PURPOSE:To simplify a fuel increment system in structure, by collectively interconnecting a part of plural suction passages to be connected in parallel at the more upstream side than a check valve to be installed inside each passage through an interconnecting pipe line, while connecting this interconnecting pipe line to a single fuel increment device. CONSTITUTION:A two-cycle V-type 6-cylindered engine 10 for outboard motor use is made up of installing three cylinders 12 at one side, while a carburetor 23 is connected to a crank chamber 20 of each cylinder 12 via a suction passage 22 where a check valve (a reed valve) 21 is built in. In this case, at a part being made up of forming the suction passage 22 of the engine 10, there is provided an interconnected pipe line 30 collectively interconnecting each of suction parts at the more upstream side than setting parts of the check valve 21, and, besides a main fuel feed system inclusive of the carburetor 23, there is provided an auxiliary fuel feed system making a float chamber 24 and an uppermost part in a vertical direction of the interconnecting pipe line 30 interconnectable. This auxiliary fuel feed system is made up of installing a single fuel increment device 32. |
